The stable operation of the power system is inseparable from the efficient operation of power electronic devices. Single-phase multi-level rectifiers are widely used in power electronic systems. Improving the stability and efficiency of single-phase multi-level rectifiers is a key research area. Based on the existing literature and research results, this article first analyzes the principle of single-phase three-level rectifiers, while then discusses the three aspects of level layers, new materials, and harmonic suppression, and analyzes the principles and characteristics of various solutions, and compare the advantages and disadvantages of various solutions, and finally discuss the application of single-phase multi-level rectifiers and optimization in various fields from three aspects: electric locomotives, wind power generation and water storage. In addition, this article also discusses the future development trend of single-phase multi-level rectifiers and the problems faced by single-phase multi-level rectifiers in current research, aiming to provide valuable reference for further research and optimization of single-phase multi-level rectifiers.
